This class extends the InetAddress class and represents an IPv4 address. It provides methods to interpret and display useful information about IP addresses.
Methods of this class take input in 4 formats:
- d.d.d.d: When this format is used as input, each of the given values are assigned to 4 bytes of the IP address from left to right.
- d.d.d: When this format is used as input, the last part is interpreted as a 16-bit number and assigned to the rightmost 2 bytes as the host address. This is generally used for specifying a class-B address.
- d.d: When this format is used as input, the last part is interpreted as a 24-bit number and assigned to the rightmost 3 bytes as the host address. This is generally used for specifying a class-A address.
- d: When this format is used as input, the given value is directly stored as a network address without any rearrangement.
Methods :
| Methods | Description |
|---|---|
| equals(Object obj) | This method compares this object against the specified object. |
| getAddress() | This method returns the raw IP address of this InetAddress object. |
| getHostAddress() | This method returns the IP address string in the textual presentation form. |
| hashCode() | This method returns a hashcode for this IP address. |
| isAnyLocalAddress() | This method utility routine check if the InetAddress is a wildcard address. |
| isLinkLocalAddress() | This method utility routine check if the InetAddress is a link-local address. |
| isLoopbackAddress() | This method utility routine check if the InetAddress is a loopback address. |
| isMCGlobal() | This method utility routine check if the multicast address has a global scope. |
| isMCLinkLocal() | This method utility routine check if the multicast address has a link scope. |
| isMCNodeLocal() | This method utility routine check if the multicast address has node scope. |
| isMCOrgLocal() | This method utility routine to check if the multicast address has organization scope. |
| isMCSiteLocal() | This method utility routine check if the multicast address has site scope. |
| isMulticastAddress() | This method utility routine check if the InetAddress is an IP multicast address. |
| isSiteLocalAddress() | This method utility routine check if the InetAddress is a site-local address. |
